Hasp retainer



Feb. 21, 1933. w H. PREs-sEvNTlN HASP RETAINER Filed April 23, 1931 [//a/lef'HPmSenzin Patented Feb. 21, 1933 PATENT OFFICE Y H. PRESSENTIN, F SEATTLE, WASHINGTON rms? RETAINER Application led April 23,

My invention relates to hasp retainers, devices which will prevent a hasp Jfrom flying ofi1 its staple, yet which do not'positively lock the hasp, but offer an easy and quickly operable means'of releasing the same when thatV becomes necessary, but which at other times will retain the hasp against accidental separation from its stap e.

In the shipment ofv motion picture films, these highly inflammable strips of celluloid are placed wthinmetal cases, Vbut because during shipment they may become heated to the point where there is danger of ignition and of explosion, it is essential (and shipping rules require) that they be so enclosed that they may be promptly taken from their cases. Vhen taken from their cases, if too hot they may burn, but they will not explode. If they are not removed from their cases and become ignited, a serious explosion will result. While it is essential, therefore, that the hasp retainer, if any is used, be such that the film can be promptly removed from the film case, it is equally desirable that the hasp be positively retained in association with its staple against accidental opening, and that this retainer offer but little impedance to one who must open the hasp. It is the object of my invention, therefore, to provide a device which will meet these conditions, which will retain the hasp at all times without the likelihood of accidental opening of the hasp, yet which will permit opening of the hasp without delay,

l and of course without the use of a key or any like means, whenever that becomes necessary.

It is a further object to provide a device having the advantages indicated above, which will be simple in construction and cheap to make and assemble, and which has no separable parts which may become lost.

My invention comprises the novel parts and the novel combination and arrangement thereof, as shown in the accompanying drawing, as will be described in this specification, and more particularly defined by the claims which terminate the same.

In the accompanying drawing I have shown my invention embodied in forms which are at present preferred by me.

Figure 1 is a face View of the hasp, staple,

andretainer in operative position, and Figure 2 is a side elevation of the same.

Figure 3 is a view similar to Figure 2, showing how the retainer prevents accidental removal of the hasp, and Figure 4 is a similar view, showing how removal of the hasp is permitted when necessary.'

Figures 5 and 6- are sections on the re spective lines 5 5 and 6,-6 of Figures 3 and 4, respectively.

Figure 7 is a section similar to Figure 5,

and Figures 8 and 9 are respectively detail side elevation and section, these last three figures illustrating a modified form. The case may be assumedto comprise a body 5 and a cover 50. The hasp 1 with its base plate 10 and hinge pin 11 is secured to one of these, as the co-ver, by such means as the screws or bolts 15, and the staple' 2 with its base plate is secured to the other, for instance, the body of the case, by means such as the screws or bolts25. YThe hasp has the usual slot 12 to receive the staple.

Arranged at an angle to the hasp slot 12 is a cross slot 13. As shown, this is at right angles to the hasp slot 12, though that is not essential. Secured upon the staple 2 is a disc 4, herein shown as round, though its shape is largely immaterial. It is apertured at 42, and the staple 2 passes through this aper-V ture to secure and suspend the disc 4. The disc is of such width or diameter, ifit is circular, that it cannot pass directly through the slot 13, and it cannot be so turned as to pass through the slot 12, though it may also be of such width that it would not in any event pass through this slot.

Preferably, the aperture 42 is at one side ofthe center of the disc 4, or is of such size that the staple 2 will engage with it well` to one side of the center of the disc. Diametrically opposite, the edge of theV disc is notched, as indicated at 41, and this notchl will ordinarily hang downward, as seen in Figurel. In this position, any tendency for the hasp 1 toA fiy ofl the staple 2 will merely engage the two sides of the disc 4, and the disc 4 will prevent separation ofthe hasp from the staple, as may be seenin Fig- '.ures 3 and 5. However, a quarter turn of the disc, from the position of Figure 5, will bring its notch 4l into position to engage one side of the cross slot 18, and now, by slight rotation of the disc, the hasp may be passed over the staple. This movement takes but an instant to accomplish, and thus, while the hasp is normally held securely, it may in an emergency be removed without delay.

In Figures 7 8 and 9, two discs, designated 4 and 40 to distinguish them, are shown, and they are mounted upon a sleeve 44, about which they may rotate to bring their like notches 41 into registry. Only in this position may they be withdrawn in the manner heretofore described, but otherwise they may not, and unless the two notches are in registry it is impossible to pass the hasp ofi' the staple.

What I claim as my invention is l. In combination with a staple and a hasp slotted to cooperate therewith, the hasp also having a cross slot intersecting the hasp slot, a retainer disc having an external notch, all diameters of said disc being greater than the length of the cross slot, the distance between the notch and diametrically opposite side of the disc being less than the length of the cross slot, a staple receiving aperture in said disc between the notch and its opposite side, to normally support the disc hanging by gravity with its notch lowermost, thereby presenting the wider portion of the disc to the cross slot to retain the hasp upon the staple, the disc upon its manual rotation upon the staple presenting the notch to the cross slot, permitting passage of the disc through the cross slot.

2. In combination with a staple and a hasp slotted to cooperate therewith, the hasp also having a cross slot intersecting the hasp slot, a circular retainer disc having an external notch, all diameters of said disc being greater than the length of the cross slot, the distance between the notch and diametrically opposite side of the disc being less than the length of the cross slot, a staple receiving aperture in said disc positioned 0E center relative to the disc and diametrically opposite the notch, to normally support the disc hanging by gravity with its notch lowermost, thereby presenting the wider portion of the disc to the cross slot to retain the hasp upon the staple, the disc upon its manual rotation upon the staple presenting the notch to the cross slot, permitting passage of the disc through the cross slot.

3. In combination with a staple and a hasp slotted to receive said staple, the hasp also having a cross slot intersecting the hasp slot, a plurality of retainer discs each of greater diameter than the length of the cross slot and each apertured at its axis to receive the staple and rotate thereon, and each notched at its periphery, the diameter of each disc between its notch and its opposite side being less than the length of the cross slot, and means to frictionally engage each disc with the other, the notches of each disc being positioned out of registry when in normal holding' position, and adapted when brought into registry to be received at one end of the cross slot whereby the discs may be passed through the cross slot.

4. In combination with a staple and a hasp slotted to cooperate therewith, the hasp also having a cross slot intersecting the hasp slot, a plurality of circular retainer discs each of greater diameter than the length of the cross slot, and each apertured at its axis and notched at its periphery, the distance across each disc between its notch and its opposite side being less than the length of the cross slot, and a sleeve rotatably mounted on said staple passing through the apertures of the several discs, about which they may rotate to bring the several notches into registry, whereby the discs may be passed through the cross slot when all the notches engage one end of such cross slot.
